Substitute Baby Mama

So, Melissa's visit to the vet resulted in homes for only three of the six kittens. The other three are awaiting rescue. They were treated for fleas at the veterinarian's office and later given baths by Melissa and I. They look effing adorable, but this is only while they sleep. I am finishing their third feeding, which averages around 2 hours of wailing/screeching/squirming/clawing/suckling/climbing/crying/pushing/nibbling....
Help. Please. Someone.
